Control valve flow coefficients

Cv-values presented in these control valve sizing coefficient tables are based on laboratory measurements usingroom temperature water according to the following phases:

1 Valve is mounted in a straight pipeline and pressure drop Δptotal is measured at the flow rate q, as shown infigure 1.

2 Valve is taken off the pipeline, and the upstream and downstream pipes are joined together, and pressure dropΔppipe is measured at the same flow rate q used in previous measurement.

Pressure drop caused by a valve alone Δpvalve is then:

Cv-value of the valve is:

where N1 = 0.865 for units [m3/h], [bar]= 1.0 for units [gpm], [psi]

While valve nominal size is smaller than attached piping, the effect of the reducer(s) to the valve capacity is takenaccount using Fp factor and then replacing Cv with Fp * Cv, which is calculated by Nelprof using standard sizingequations. In a case where pipe diameter D is the same size on both side of the valve, the following graph (figure 2)can be used for a quick evaluation.

Δpvalve Δptotal= Δppipe–

Nomenclature used in the control valve sizing coefficient tables

Marking used to identify reduced Cv-trims

The reduced Cv-trims can be identified from the '/' sign after the valve nominal size in the SIZE column in the Cv-tables. The number after the '/' sign represents the reduction number of the Cv-trim. For example, in the Cv-table forR-series V-port segment valves, the marking 25/1 (1/1) in the size column represents the first reduced Cv-trim for theR-series size DN 25 (1") V-port segment valve. Correspondingly, the marking 25/4 (1/4) represents the fourth reduc-tion.

In Nelprof, enter the '/' sign and reduction number after valve nominal size for the valve size. For example, for firstreduction for a DN 25 (1") valve size, enter 25/1 or 1"/1 for valve size.

Other nomenclature

Cv = Valve flow coefficient, which represents valve capacity

h = Relative opening, which is calculated for rotary type of valves as follows:h =100% * (actual opening in degrees - h0) / (maximum opening in degrees - h0)where the h0 represents the initial opening in degrees. Some rotary valves have to be opened by theamount of initial opening h0 before the fluid begins to flow through the valve. The initial openingvalues for different valve styles are listed at the end of this book.

Cv/d2 = Cv divided by the square of the valve inlet diameter d in inches

The factors FL, xT, and z are presented as a function of Cv/d2 in order to count for different geometriesin different size control valves. The Cv/d2 values correspond to average Cv/d2 relation of the valve at10 % opening intervals, and can be used for rough manual calculations as such. The Nelprof programinterpolates sizing factors based on accurate Cv/d2 values

FL = Pressure recovery factor according to standards IEC 60534 and ISA S75

xT = Pressure drop ratio factor according to standards IEC 60534 and ISA S75

z = Valve specific characteristic pressure drop ratio used in hydrodynamic noise prediction according tostandard VDMA 24442

ΔLf = Hydrodynamic noise coefficient, which is a valve type related factor in control valve hydrodynamicnoise prediction

xf = Pressure drop ratio, which is calculated as follows:xf = (p1-p2)/(p1-pv), in which pv represents vapor pressure.Hydrodynamic noise coefficient ΔLf affects liquid fluid control valve noise level only if pressure dropratio xf is greater than z

XR = Scaled pressure drop ratio for cavitating flow, which is calculated as follows:XR=(xf-z)/(1-z)

ΔLg = Aerodynamic noise coefficient, which is a valve type related factor in control valve aerodynamicnoise prediction

x = Pressure drop ratio, which is calculated as follows: x=(p1-p2)/p1

SERIES AB ANGLE PATTERN CONTROL VALVES, BALANCED STANDARD TRIM, LINEAR(Nelprof® code AB-STD-LIN)

Series angle pattern-balanced cage guided globe valves areeconomical high-performance control valves designed toprovide the best possible control accuracy and wide range-ability. The standard cage trim is designed with a speciallyrepresented window shape cage and balanced plug. Thewindow shape defines the flow path through the valve andthe flow characteristic of the valve. The balancing holes arelocated in the top of the plug. This trim is suited for bothhigh and low pressure drop application and is used in themajority of control applications. Temperature limits - 29 ...+260 °C with standard bonnet construction. ASME class150-600. Many end connection styles available for differentapplications.
